Field sobriety tests are roadside assessments designed to help officers observe signs of impairment, commonly including the walk-and-turn, one-leg stand, and horizontal gaze nystagmus. These tests rely on standardized procedures and correct environmental conditions to provide meaningful observations. In practice, results can be affected by non-alcohol-related factors such as surface conditions, footwear, lighting, or the subject’s physical condition, which is why their reliability is often questioned during legal review. Officers use these tests as initial indicators to support reasonable suspicion or probable cause, but the tests are not definitive proof of intoxication. Courts and administrative panels often consider the circumstances of administration, the presence of video, and medical explanations when weighing the significance of field sobriety test results. In Magnolia, careful documentation and review of how the tests were conducted is important to challenging their evidentiary weight.
